Most bitcoin public keys are sitting behind two levels of hashes: SHA256 and Ripemd-160. So both would need to be broken to even get the PUBLIC key. The elliptic curve cryptography would also need to be simultaneously proven flawed in order to spend the coin.
The blocks in the blockchain, however, just use SHA256 to chain themselves together.. so there might be some advantage to the miners if this was flawed though it might only enable double-spend attacks which would be detectable.
The original Oculus Rift prototypes used a sensor that was readily available on the market, but ultimately we decided to develop our own sensor hardware to achieve an optimal experience. With the new Oculus VR sensor, we support sampling rates up to 1000hz, which minimizes the time between the player’s head movement and the game engine receiving the sensor data to roughly 2 milliseconds.
The increased sampling rates also reduce orientation error by providing a denser dataset to integrate over, making the player’s real-world movements more in-sync with the game.
I believe the summary put a comma in the wrong place...
9-axis motion detect with low latency (1 ms), wireless communication
Should be:
9-axis motion detect, with low latency (1 ms) wireless communication
The article mentions nothing of 1ms latency head tracking... it does mention the wireless communication latency being 1ms, however. This is a very important distinction as the latency of head tracking is what the Occulus Rift has appeared to have put the most effort into via their custom 3-way merged sensor chip.
Oh and I do love the saying "correlation is not causation" often said here, which is where crackpot anti-logic spills over into the/. group think. Correlation is in fact a prerequisite of causation, certainly a lack of correlation is evidence against causation?
The actual saying goes "Correlation does not denote causation", which I hope you agree, makes more sense.

I'd imagine it is more effective to attack their web server than their bandwidth. The more connections the better, and don't close them.. let the web server timeout on each.
Like I said, the article didn't say, but I doubt they are using object detection like facial recognition. It's easy to toss around concepts like "see humans", and impossible to get software to do it 100% of the time. I'd be willing to bet they are using infrared to detect heat, and motion to detect the size and direction of the moving objects. Maybe when the TED talk comes out we will have more info.. can't wait.
What do you think about intermediate variables that are not strictly necessary?
I'll often find myself coding some physics equations from specifications written on paper. Obviously, they are always written in math notations. What I end up doing, if not limited by cpu/ram, is to create a stack variable for each term in the equations. Basically, I'll try to make the code look as much like the paper specs as possible. The specs will ALWAYS change, and trying to figure out how the two relate some years later is a real pita. Also, I'll always preface everything with some comment like "The following is from foobar specs dated Jan 1st 2002" for the reverse reasons.
Well I didn't read anything about stereoscopic vision, so I'm guessing it is using the motion of the mosquito to track. If that is the case, then you could get hit if you stand completely still.
I'd be completely wrong if they are using infrared vision, or facial recognition, but the article didn't mention.
The problem, however, will be the increasing backlash Google is seeing from the general public over how much data the company already controls on their online habits.
Doesn't seem like a problem for them so far. I'm fairly sure only a tiny percent of the people using social networking services really care about privacy. Even Facebook CEO Mark Zuckerberg came out and said Privacy is no longer a social norm. The real hurdle for Google Buzz is going to be migrating the massive social graph that exists on Facebook. The usefulness of these sites is mainly due to who is participating. I'm guessing that's why they injected Buzz directly into gmail.. where they already have a sizable dominance.

It has been a long time since it was just an RSS reader. From 2007: Google Reader Begins Sharing Private Data. The newer features added in the past few months have pushed it more to the social side, IMO. Of course it all depends on how you use it, and who you are sharing data with.. and how they use it.
Google Reader is an RSS aggregator, not a social networking site.
The group of people I currently see sharing content on Google Reader suggests otherwise. It has been moving towards the social aspect for awhile now. eg. Sharing content, commenting, 'liking'. It feels like a precursor to what Google Wave is trying to be.
How many social networking sites are we gonna go through before we settle on an open platform? Anybody remember Friendster? Myspace, Orkut, Facebook, Google Reader. Oh, I found a really long list of them.
I honestly can't believe that Facebook will be worth much considering how many other sites we've already gone through. I'm usually wrong though, so who knows.
I wasn't referring to the search results. What I listed were from _before_ you search.. ie. the search "hints" that pop up before clicking on "search".
What you describe seems very similar to what OpenMP provides for recent C/C++ and Fortran compilers. It is probably available in your C/C++ compiler already.

So the NSA went through all this effort... to double spend bitcoin?
Most bitcoin public keys are sitting behind two levels of hashes: SHA256 and Ripemd-160. So both would need to be broken to even get the PUBLIC key. The elliptic curve cryptography would also need to be simultaneously proven flawed in order to spend the coin. The blocks in the blockchain, however, just use SHA256 to chain themselves together.. so there might be some advantage to the miners if this was flawed though it might only enable double-spend attacks which would be detectable.
Trying to bring attention to this thread whether it turns out true or false.

Noticed it also though I thought maybe Tesla had added engine noises to the vehicle.
As with seismic data, they might only emit with one device and the rest are a passive array of receivers. http://en.wikipedia.org/wiki/Reflection_seismology#Marine_survey_acquisition_.28streamer.29
